Answer:
D The new line would be less steep than the original line.
Step-by-step explanation:
Assuming the slope is change from 3 to 1/3, the new line would be less steep.
__
The steepness of a line increases as the magnitude of the slope increases. The slope 1/3 is less than 3, so a line with that slope is less steep than a line with a slope of 3.

5. Zhao purchased a used car for $11,500. This make and model used car
straight line depreciates to zero after 9 years. (a) Identify the coordinates
of the x and y intercepts. *
Answer:
(9, 0)
(0, 11200)
Step-by-step explanation:
The x - intercept is the value of x when y = 0 ; similarly, the y - intercept is the value of y, when x = 0
From the given relation :
y = price, x = number of years
Price after 9 years of usage, the price of car is depreciated to 0
Hence,
x = 9, y = 0
(9, 0)
At purchase, the value of car is 11,200 ;
At this price, the number of years of usage of car is 0
Hence ;
x = 0 ; y = 11200
(0, 11200)

For what values of x is the expression below defined?
Answer:
x > 0
Step-by-step explanation:
Given :-
√[3x²] ÷ √[4x ]And we need to find the value of x for which the expression is defined . The expression is ,
[tex]:\implies[/tex] √[3x²] ÷ √[4x]
As we can see that x is inside the squareroot. So for defining the expression the value of x should be Greater than 0 . As negative inside the squareroot will give rise to imaginary numbers.
Solution :-
[tex]:\implies[/tex] x > 0
In interval notation :-
[tex]:\implies\bf x \in ( 0 , \infty) [/tex]
Therefore x should be Greater than 0 .

About 26% of movies coming out of Hollywood are comedies, Warner Bros has been the lead studio for about 13% of recent movies, and about 3% of recent movies are comedies from Warner Bros. Let C denote the event a movie is a comedy and W denote the event a movie is produced by Warner Bros.
Required:
a. What is the probability that a movie is either a comedy or produced by Warner Bros?
b. What is the probability that a Warner Bros movie is a comedy?
c. What is the probability that a comedy has Warner Bros as its producer?
Answer:
a. 0.36 = 36% probability that a movie is either a comedy or produced by Warner Bros.
b. 0.2308 = 23.08% probability that a Warner Bros movie is a comedy
c. 0.1154 = 11.54% probability that a comedy has Warner Bros as its producer
Step-by-step explanation:
Conditional Probability
We use the conditional probability formula to solve this question. It is
[tex]P(B|A) = \frac{P(A \cap B)}{P(A)}[/tex]
In which
P(B|A) is the probability of event B happening, given that A happened.
[tex]P(A \cap B)[/tex] is the probability of both A and B happening.
P(A) is the probability of A happening.
a. What is the probability that a movie is either a comedy or produced by Warner Bros?
We solve this question treating these events as Venn sets.
I am going to say that:
Set A: Movie is a comedy.
Set B: Movie is produced by Warner Bros.
26% of movies coming out of Hollywood are comedies
This means that[tex]P(A) = 0.26[/tex]
Warner Bros has been the lead studio for about 13% of recent movies
This means that [tex]P(B) = 0.13[/tex]
3% of recent movies are comedies from Warner Bros.
This means that [tex]P(A \cap B) = 0.03[/tex]
The desired probability is:
[tex]P(A \cup B) = P(A) + P(B) - P(A \cap B) = 0.26 + 0.13 - 0.03 = 0.36[/tex]
0.36 = 36% probability that a movie is either a comedy or produced by Warner Bros.
b. What is the probability that a Warner Bros movie is a comedy?
Conditional probability, in which
Event A: Produced by Warner Bros
Event B: Comedy
Warner Bros has been the lead studio for about 13% of recent movies
This means that [tex]P(A) = 0.13[/tex]
3% of recent movies are comedies from Warner Bros.
This means that [tex]P(A \cap B) = 0.03[/tex]
The desired probability is:
[tex]P(B|A) = \frac{P(A \cap B)}{P(A)} = \frac{0.03}{0.13} = 0.2308[/tex]
0.2308 = 23.08% probability that a Warner Bros movie is a comedy.
c. What is the probability that a comedy has Warner Bros as its producer?
Now,
Event A: Comedy
Event B: Warner Bros as its producer.
About 26% of movies coming out of Hollywood are comedies
This means that [tex]P(A) = 0.26[/tex]
3% of recent movies are comedies from Warner Bros.
This means that [tex]P(A \cap B) = 0.03[/tex]
The desired probability is:
[tex]P(B|A) = \frac{P(A \cap B)}{P(A)} = \frac{0.03}{0.26} = 0.1154[/tex]
0.1154 = 11.54% probability that a comedy has Warner Bros as its producer

A satellite circles the earth in such a manner that it is y miles from the equator (north or south, height from the surface not considered) t minutes after its launch, where y is given by the equation below.
(picture)
At what times t in the interval , the first 4 hr, is the satellite mi north of the equator?
9514 1404 393
Answer:
t ∈ {19, 85, 109, 175, 199}
or
t ∈ {40, 64, 130, 154, 220}
Step-by-step explanation:
A graphing calculator relieves the tedium of solving for t. The attachments show the times the satellite is 4000 miles from the equator. Since y may be either north or south, the satellite may be 4000 north of the equator for y = 4000 or for y = -4000.
__
If y is miles north of the equator, then ...
4000 = 6000cos(z) . . . . . where z=(π/45)(t-7)
z = arccos(4000/6000) ≈ 0.84107 radians
There is another solution at 2π -0.84107 radians, about 5.44212 radians
The corresponding time values are ...
t = 7 +(45/π)(z) ≈ 19.047 and 84.953 . . . . minutes
The period of the function is 90 minutes, the times will be the above times and at 90-minute intervals after each.
The satellite is 4000 miles north of the equator at ...
t ≈ 19, 85, 109, 175, 199 . . . minutes after launch
__
The solution is similar if y represents miles south of the equator. Then we have ...
-4000 = 6000cos(z)
z = arccos(-4000/6000) ≈ 2.30052 radians (and 3.98266 radians)
The corresponding time values are ...
t = 7 +(45/π)(z) ≈ 39.952 and 64.047 . . . . minutes
Again, considering the period, the satellite is 4000 miles north of the equator at ...
t ≈ 40, 64, 130, 154, 220 . . . minutes after launch
_____
Additional comment
We might usually think of y as being positive in the northerly direction. However, in this age of political correctness and bias sensitivity, we have to consider that "y is north or south" means exactly that. So, we have also shown the solutions when y is positive south of the equator.
Usually, we prefer that the variables are defined unambiguously.

by how much is the product of 9/5 and 33/4 greater than 5
Answer:
The product of 9/5 and 33/4 is 9.85 units larger than 5.
Step-by-step explanation:
To determine by how much is the product of 9/5 and 33/4 greater than 5, the following calculations must be performed:
((9/5) x (33/4)) - 5 = X
(1.8 x 8.25) - 5 = X
14.85 - 5 = X
9.85 = X
Therefore, the product of 9/5 and 33/4 is 9.85 units larger than 5.

Find an
equation for the line through (-6, 3) and
parallel to y = 3x + 1.
Since this line is parallel to y = 3x + 1 their slopes are equal. The slope is equal to 3. The line is also passing the point (-3,4).
This is the format of the line parallel to y = 3x + 1
y = 3x+ b
This line passes through point (-3, 4)
Replacing the values of y and x coming from the coordinates of (-3, 4)
4 = 3 * (-3) + b
Solving for the y-intercept b
4 = -9 + b
b = 4 + 9
b = 13
Knowing the slope as equal to 3 and the y-intercept as 13 the equation of the line is
y = 3x+13

The average daily iron intake for 12-year-olds is 15.1 milligrams. Fernando typically consumes 11.8 milligrams of iron in his breakfast cereal and 3.6 milligrams of iron from a protein bar. If he eats a bowl of cereal and two protein bars today, how many milligrams over the average daily intake for iron will Fernando's intake be?
Answer:
3.9 milligrams more than the normal or whatever it said
Step-by-step explanation:
you multiply 3.6 by 2 and you get 7.2 then you add 11.8 to that 7.2 which give you 19, then subtract 15.1 from 19 which would give you 3.9 milligrams

Since it's reflected across the y-axis, the y value stays the same and the x value changes to a negative. If it were reflected across the x-axis then the x value you stay the same and the y value would change to a negative. Since it's a reflection, meaning it's just "mirrored" across a given point, the numbers stay the same regardless.

Answer: Scalene and isosceles
Step-by-step explanation:
Identify the distance between the points (9,7,3) and (5,3,2), and identify the midpoint of the segment for which these are the endpoints. Round to the nearest tenth, if necessary.
Using it's formula, it is found that the distance between the two points is of 5.7 units. Additionally, the midpoint is (7, 5, 2.5).
What is the distance between two points?Suppose that we have two points, [tex](x_1,y_1)[/tex] and [tex](x_2,y_2)[/tex]. The distance between them is given by:
[tex]D = \sqrt{(x_2-x_1)^2+(y_2-y_1)^2}[/tex]
In this problem, the points are (9,7,3) and (5,3,2), hence:
[tex]D = \sqrt{(9 - 5)^2 + (7 - 3)^2 + (3 - 2)^2} = 5.7[/tex]
The distance between the two points is of 5.7 units.
What is the midpoint?The midpoint is the mean of the coordinates, hence:
xM = (9 + 5)/2 = 7.yM = (7 + 3)/2 = 5.zM = (3 + 2)/2 = 2.5.The midpoint is (7, 5, 2.5).
